As mentioned, it will not work unless as someone is added to the mailing list.. they are added as a user.

This would be a management nightmare.

If any email address was not a valid user, they would get email messages from the site.

The mailing lists you encounter set the reply-to, but they do not change the "from" sometimes they will change the representation of the from. But typically, in the header information, that is not changed.

So. No. It would not feasibly work and unfortunately it's not something I plan on coding as it would be irrational to have both running. Those free hosts all have a board system there.

The primary argument I've used in convincing those that use them to switch is who owns the servers.

They may be using those boards but the servers are owned by that free host and they can allow that information to be released to anyone at any point in time.

In moving to a vbulletin hosted mailing list, you have sole control over the information and who can access what.
